dent ofthe city ofv New York, borough of Manhattan, in the county and State -`of New a ,newl andA Improved following is a full,

^ clear, vand exact description.

This invention relates to envelope.

The object of the invention is to provide' an envelopwith'an ungumnied flap which -may be held within'a' pocket, or may be removed therefrom in order to allow the con tents of the 'envelop to be inspected by the l envelop is also'pro vided with' an ordinary gummed flap, which postalvl authorities. The

i ispinte'nded to' lloe sealed '1n order to give the envelop the appearance of a' sealed envelop and 'yet allow V,the same to he sent throng the mailI atl thelposta'ge rat-es required for unsealed matter.

I and/combination of The invention consists in the construction y y y parts, to be more fully described hereinafter and particularly set forth 'in the"claim`s. I c p Reference is ytobe had tothe accompany- I ling drawings forming' a part` of this specification, `1n which" similar characters of refuerencve.indicate1 corresponding partsl in all 4t'heviews', and in whlch;

rlhe envelop maycomprise a front' portion 1 having end flaps `2 .and 3, a top flap 4, and a bottom iap 5, all formed integrally from one piecel of n1aterial. The liaps 2 and 3 may be formed with extensions 6 and '7,

shown in dotted lines in Fig. l and also in full lines after they have been turned over against the inner faces of theiiaps 2 and 3. The dotted lines in Fig. l show the position of the flap 5 and the extensions 6 and 7 when the blank isiirst cut. It will be. noted that the extensions 6 and 7 are not as deep as the flap 5 in thefpresent embodiment, but said extensions may be made the same depth as the flap 5 is desired. The flap 4 is provided with a glunmed strip 10 Specification of Letters Patent. i Application filed January 28, 1909. Serial o. 474,693.`

of the usual character. The yflap 2fvhas a gummed strip 12.eXtendingJalongv the inclinededge of said Hap, togetherwitha strip 13 extending alongitheouter edgefof the flap, and a strip 14l extendingfrom the o'uter edge partially'across said tla'pfat a distance above the lower' edgev of said flap equal to or greater than' thedepthof the Hap 5. The flap 3 has afgunnn'ed strip 16 gumnied` strip 17 along its outer edge. A gum'medtstrip 18 extends intermediatethedcligth 'cf the strip 17 partially across th'eap 3"`substan tially in line with the strip`14 onA theiiap 2. v In itspresent embodiment, the 'envelop isv provided with an "insert oi' jfacing "strip 20, which in the present instance'is substantially the saine length as'the longest'-dime11- sion of the front portionil ,but somewhat narrower than the shortest dimension 'of said front portion.- y have its ends 22 and 24 roundedI somewhatl as shown in Fig. 1. y 'I y In, constructingA the envelop' vfrom he blank having the flap ,5 and the eXtenS ons 6 and 7 in the dotted-line'pcsiton sho ',1 in Fig. 1, said flapl 5 and'theextension's'and 7 are folded over into lthe positionishoyvn in the full llines in Fi'gnyl,'bynonefoperation At 'the same time thefa'cingwst 'ip 20"is inserted underneath the 'tlap"A g'fthereupon the flap 2 is foldedjoyer,l shown 'in Figs. and 3, andN the gummedV strips l2, 1.3. `and 1,14-.securexsaid iap to the facing20;thereupontheflap' Patented Nav. 30,1909.

. the outer face of the flap 2, Aandlsfaid'strip` Y By reference to Figs. 2f and 4,z it be seen lthat when the sealing'lap-4 is open, the facing strip 20 protects the removable flap 5, so that the matter 't be mailed may be readily inserted in the envelop, being retained betweenthe front portion 1 land the facing strip 20. Thereupon, the sealing flap 1 0 may be secured in the position shown in Fig. 3, or in the dotted-line position shown in Fig. 4. If it be desired to inspect the contents of the envelop after it is sealed, it is merely necessary to withdraw the inspection flap 5, as shown in Fig. 3, where-l upon thecontents of the readily withdrawn.

envelop 'may be The lower edges Aof the flaps 2 and'3 in the finished envelop are -reinforced by the eX- tensions 6 and 7. This construction producesa'n envelop which is much more durable than would be the case if the flaps 2 and 3' were of a single thickness at their lower edges.

" Itwill be noted thatthe envelop is so constructed as to. allow the contents to be 'readily inserted and inspected, vyet provides a. durable constructionwhich overcomes the 'objectionable features which are present in .the envelops now commonly in use.

I {aving thus described my invention, 1 claim as new and desire to-secure by Letters Patent 1. An envelop, comprising a front portion,

a. backv portion formed lof flaps carried by the .front portion, and a separate .facing strip, two ofsaid flaps and said facing strip 'being secured together to form a pocket in said back portion .between said flaps and said facing strip, and open alongone edge of the envelop to removably recelve another las of. '-said flaps,- the remaining `flap being gummed and adapted to be secured to the 4remainder of the back portion after an in- .Closure has been placedwithin the envelop.

2. An envelo comprising a front portion, top, bottom an end flaps, all formed integral therewith, and a' separate facing strip,

two of saidfiaps being secured to said facing `strip to form a pocket therewith open along one edge of the envelop, one of the remain- 40 ing flaps', being normally received within said pocket. and concealed from` view both 'from' the 'interior and theexterior of the envelopand removable from said pocket for inspection purposes. and the other flap being secured 'in position to close the envelop after the insertion of inclosures.

An envelop having ,a front portion, an

. ungummed flap 0n one of its edges, va

gumniedlap on one of its edges' and end flaps, all made integrally from one piece.

,of material, in combination -with la separate piece of material attached to the end'ilaps and forming therewith the back` portion of said envelop a'nd a pocket in said back por tion within which is received said unsaid envelop having an opening' left in one edge thereof` through' which an inclosure maybe placed within the envelop without removing said ungurnrned flap from said pocket., saidopening beingclosed by said gummed flap after the insertion of the inclosure.

L'Anenvelop having a front portion, four flaps integral therewith, and a separatel Agunnncd flap inthe course of manufacture,

piece of material forming with two ofsaid flaps the back portion ofv the envelop and presenting a pocket w1th1n said back portlon open along one edge of the envelopl for removably receiving' a third one of said flaps in the course of manufacture of the envelop, said first-mentioned iaps each having an extension along one edge 'thereoffolded back upon the'body of the flap to form a reinforcement at the open edge of the' pocket,

and the envelop havlng an opening 1n one edge thereof closed by the fourth fiapafter the insertion of inclosures.

5. An envelop having-a front portion, end flaps integral therewith and each of a length slightly greater than one-half the length of the front. portion, and each having one edge thereof disposed adjacent one ,edge of the front portion when said end flaps are folded toward each other, a separate piece of material interposed between said end flaps and said front portion, and gumlned to both of said end fiaps along'the, length of the envelop, but unattached to the end flaps al'ong the above-mentioned edges of the latter, so as'to leave a pocket between said'separate piece andl said end flaps, an ungummed inspection flap integral with said front portion and normally disposed within said poclret,and a gummed flap. integral with said front portion and adapted to be secured to said end flaps after the insertion of inclosures.

In testimony whereof I have signed my named to this specification inthe presence of two subscribing witnesses.
